Or noticed someone sneaking around trying not to be seen?

In Japanese, these sounds and actions are captured perfectly:

Cultural Note

In English, you might say:

  • “Whisper” vs “Sneak”
  • “Talk in hushed voices” vs “Move secretly”

But in Japanese, these expressions carry sound and emotional texture:

ExpressionFocusWhat it DescribesCommon Feel
Hiso HisoVoice / SpeechQuiet, private talkingMysterious, gentle
Koso KosoMovementSneaky, secretive actionSuspicious, guilty

That’s why in anime and manga, you’ll often see:

  • ひそひそ in speech bubbles with tiny fonts
  • こそこそ used in narration when someone moves like a thief!

Examples in Daily Life

Example 1: Whispering in class (Hiso Hiso)

They giggled and whispered behind the teacher’s back —
hiso hiso…

Example 2: Sneaking for midnight snack (Koso Koso)

He tiptoed to the fridge at midnight —
koso koso…

Try Using Them!

Someone whispering in the library? → Say hiso hiso…

Someone sneaking out of a room? → Say koso koso…
